Happy Birthday, Pluto, but you're still not a planet.
Pluto was discovered 80 years ago today, and astronomers are still arguing over what it is.

The oddball world, downgraded from planet to dwarf planet status in 2006 and then later reclassified, is really out there. Scientists aren't sure exactly what Pluto's made of, how it formed, or why it orbits so oddly compared to the eight primary planets. And there are at least two camps of astronomers when it comes to defining Pluto. Some just think of it as a planet, others call it a dwarf planet or a plutoid.
Plutoid. What a great insult. Or possibly somthing akin to a hemorrhoid.
